PORTER MORRISON, OF ATHENS, TEXAS.

corroN-onv.

To all whom it may concern:

Be it known that .I, PORTER MORRISON, a citizen of the United States,residing at Athens, in the county of Henderson and State of Texas, haveinvented new and useful Improvements in Cotton-Grins, of which thefollowing is a specification.

This invention relates to cotton gins, and the principal object of theinvention is to produce a cotton gin of small dimensions which may beconveniently operated by hand, but which shall be entirely effective forthe purpose of. removing the lint from seed that it is desired to savefor propagating purposes.

A further object of the invention is to produce a simple and convenientgin of small dimensions which while entirely efiective to remove thelint will not be liable to injure the seed.

With these and other ends in view which will readily appear as thenature of the invention is better understood, the same consists in theimproved construction and novel arrangement and combination of partswhich will be hereinafter fully described I and particularly pointed outin the claim.

In the accompanying drawings has been illustrated a simple and preferredform of the invention, it being, however, understood that no limitationis necessarily made to the precise structural details therein exhibited,but that changes, alterations and modifications within the scope of theclaim may be resorted to when desired.

In the drawings,-Figure 1 is a side elevation of a cotton ginconstructed in accordance with the invention. Fig. 2 is a top plan viewof the same. Fig. 3 is a front end view. Fig. 4 is a transversesectional view taken in advance of the rotary brush and looking in thedirection of said brush. Fig. 5 is a longitudinal sectional view.

Corresponding parts in the several figures are denoted by likecharacters of reference.

The casing of the improved gin is of substantially rectangular shape,and said casing has been shown in the drawings as being composed ofplates or side members 5, 5 and front and rear plates 6, 7, said platesbeing formed of sheet metal, such as steel plate of suitable gage, andthe end members being terminally bent to produce flanges 8 for thepassage of bolts 9, whereby said end members are connected with the sidemembers.

A simple, light and efficient casing of great Specification of LettersPatent.

strength is in this manner produced. The side plates 5 are provided withapertures for the passage of the several shafts to be hereinaftermentioned, and said apertures are exteriorly reinforced by journal boxes10 preferably of cast iron, said boxes being mounted in position bymeans of bolts, rivets or other suitable fastening devices, notspecifically indicated. The main driving shaft 11 has at one end a crank12 whereby it may be rotated. The other end of the shaft 11 carries aspur wheel 13 meshing with a pinion 14 on a counter shaft 15, whichlatter also carries a spur wheel 16 for the purpose of transmittingmotion at accelerated speed to the saw shaft 17 which carries a pinion18 meshing with the spur wheel 16. The latter also meshes with atransmission pinion 19 which in turn meshes with a pinion 20 on thebrush shaft 21 for the purpose of rotating the latter in the properdirection.

The saw shaft 17 carries the saws 22 which partially project throughslots 23 in an inclined breast plate 24 which in this instanceconstitutes the bottom of the feed hopper 25, which latter is bounded bythe two side plates 5 and the front plate 6 of the casing, together withan upward vertical extension 26 of the breast plate 24. Secured on thefront plate 6 is a deflector 27 which extends obliquely in a downwardand rearward direction toward that portion of the saws which projectsthrough the slots 23.

The shaft 21 carries the cylindrical brush 28 which is in peripheralengagement with the saws for the purpose of removing the lint from thelatter. A comb 29 is also employed for the purpose of detaching the lintfrom the brush.

While the operation of this gin does not differ in any essential detailfrom machine gins of well known construction, it will be seen that Thave provided a very compact and effective device of small dimensionswhich has been found extremely efiective for the purpose of detachingthe lint from the seeds. The device may be manufactured and supplied ata cost which will permit acquisition by the individual cotton grower,even if operating on a comparatively small scale.

tion is practically impossible when the entire crop is ginned at thelarge gin house, andit is believed that by the use of this simplemachine, the cotton culture may be greatly benefited. v

Having thus described the inventiom what is claimed as new, is

, A miniature cotton gin for saving seeds for propagation, the sameCOmPriSing a rect'angular casing having side members and 'end membersformed 0]": sheet metal, said end members being provided with flangesabutting on the side members and bolted thereon, the front end memberhaving a clown- Wardly and rearwardly extending deflector, an inclinedslotted breast plate positioned in rear of the deflector and havingupwardly and downwardly extending portions bolted upon the side members,cast metal boxes riveted on the sheet metal side members and affordingbearings for a saw carrying shaft and a brush carrying shaft, gearingfor transmitting motion between said shafts and for driving and properlyspeeding the same, and a comb fixed on the rear end wall of the casingand extending in the direction of the rotary brush which it engages.

In testimony whereof I ailix my signature in presence of two witnesses.
